Proportional Solenoid Valve (patent WO 2009/087465)

We patented a proportional valve for gas
and fluid mass flow control. The valve controls the mass flow of fluids using an
electric signal. The principle of operation is based on flux shunting.

The valve operates safely as it
is normally closed (if the supply goes off, it shuts). Its uses are manifold, ranging from home appliances (gas kitchens, ovens, gas boilers) to automotive (fuel
control) and industry.

We demonstrated that our valve can control the
temperature of a gas oven as precisely as in an electric oven. Gas boilers are the main application for the valve, as it can control very
precisely the gas flow, increasing efficiency and improving combustion at low
loads. Other devices on the merket require an additional electrovalve.

Our electrovalve withstood all tests for kitchen devices. So it is also compliant with the
international standards for gas ovens, etc. The patent is valid worldwide.

Currently,
there are two versions of the valve: the smaller is suitable for a room
temperature lower than 110°C and has a diameter of 30mm, the larger is suitable
for temperatures above 110°C and its diameter is 38mm. The power consumption is
5W for the larger version. The valve is able to effective and fast control of a fluid flow. The valve has been tested with different kitchen burners including the oven burner.
